Don't think so, the LISTEN_FDS is dead simple; if LISTEN_FDS is set in the environment, fd#3 to fd#3+LISTEN_FDS are sockets opened by the calling process, and their function has to be deduced via getsockname and sockets should not opened by the process. If LISTEN_FDS is not set, proceed to open sockets just like before. The good thing about this is that systemd can reserve the ports used very early during boot, and no other process can steal them away. For testing purposes, this could be used to assure that all ports are available before starting tests (if random port stealing is the true problem here, that is still an unverified shot in the dark). > > Unless there's a better, cross platform approach of course. :) > > Regards and best wishes, > > Justin Clift > /Anders -- Anders Blomdell Email: anders.blomdell@xxxxxxxxxxxxxx Department of Automatic Control Lund University Phone: +46 46 222 4625 P.O.
